Shape.LeftRelative Property (Word)
Returns or sets a Single that represents the relative left position of a shape. Read/write.
Use this property with the RelativeHorizontalPosition property. When set to wdShapePositionRelativeNone (-999999) (see the WdShapePositionRelative enumeration), this property should be ignored because the shape does not use percent positioning. The horizontal position is solely determined by the Left property.
